LANTERN.

SPECIFICATION forming part of Letters Patent No. 493,495, dated March14, 1893.

Application filed March 28, 1892.

To all whom. it may concern.-

Be it known that I, JOSEPH FUNOK, a citizen of the United States,residing at New Brighton, in the county of Richmond 7 and State of NewYork, have invented anew and usefullmprovement in Lanterns, of which thefollowing is a specification. Y

My invention relates especially to such lan-. terns as are used formarine purposes, to be placed upon piers,buoys, vessels, and in otherexposed places for signals. I-leretofore it has been difficult to keepsuch lanterns burning, especially for all night periods, because of themovement to which they are frequently subjiected and because of theviolence of the win The object of my invention is to construct a lanternthat will burn under all conditions until the oil is exhausted and notbe extinguished, thus overcoming the before named objections.

In carrying out my invention I employ a removable oil fount with acentral oil and wick chamber and vertically disposed air tubes passingthrough the oil fount air chambers and a divisional plate of perforatedmetal and the upper part of the fount adjacent to the burner is providedwith a downwardly turned air deflector disposed over the upper ends ofthe vertical air tubes. The lower and upper shells of the lantern areperforated for the entrance of air the force of which at the base of theoil fount is broken by protecting outer and inner plates so disposed asto leave channels for conveying and directing the ingress of air. I alsoprovide conical tapering tubes within the upper part of the lantern anddomes or hoods for the escape of the products of combustion without riskof air blowing into the top of the lantern.

In the drawings Figure 1 is a vertical section of my improved lantern.Fig. 2 is asectional plan at the line 00 a: of Fig. 1, and Fig. 3 is avertical section at the line y y of Fig. 2.

The main portion of my lantern is composed of the lower shell a andflaring base a, the cylindrical lens glass 1), the upper shell 0,defiector c and the wire framing or cage 01 extending vertically andhorizontally and secured to the shells, and the upper knob 2. All theseparts are of well known construction and do not require furtherdescription.

"edge of the base 9.

Serial No. 426,666. (No model.)

The removable oil fount f is made with a flaring imperforate base 9 andcircular inclined flange h, and two or more pins 2, and the lower shellis made with a notched plate 3. The rib h comes up beneath the plate 3into the angle formed by the junction of the shell a and plate 3 and thepins 2 pass through the notches in the plate 3 and over the plate 3 ininserting the fountfto place, a bayonet locking device being thus formedand the air excluded at the periphery of the rib h. The bottom of theoil fount is recessed at f to form an air chamber and a perforated plateof metal 2' is inserted and secured therein so as to be flush with thebottom of the oil fount, and the flaring base 9 forms an air chamberbelow the plate 1' and the base a of the lantern shell is perforated at15 for the ingress of air which passes down beneath the lower The oilfount f has a central oil and wick chamber It, extending down from theupper part at the burner to near the bottom of the fount. This chamberdivides the body of oil and prevents the splashing of the oil at thejunction of the burner Z and fountfwhere oil would be likely to pass outas the result of concussion vibration orswaying. The burner Z has alower portion sitting Within the chamber 70 and is secured in place onthe fount preferably by wire clamps l which are sprung over the flange Zand the wick m is operated by gear wheels m or pinions at right anglesand by a rod m passing down through a tube in the oil fount and having athumb wheel or button at the lower end beneath the fount so that theflame can be regulated without removing the fount. Air tubes 71. extendthrough the airfount outside the chamber is, their lower ends openingthrough the bottom f and their upper ends through the top of the fountbeneath the outwardly turned air deflector 0, so that air enters theperforated base a, passes beneath the lower edge of the base 9, throughthe perforated plate '6 and air tubes at and beneath the deflector 0escaping beneath its lower edge and rising to the flame.

The lower shell a of the lantern is perforated circumferentially at thesection line 00 0c, and there is an outer hanging shield plate 4' andinner hanging shield plate 1" connected to the shell Ct above theperforations therein and extending below these perforations thus formingcircuitous channels for the ingress of air into the lower part of thelantern. The lower edge of the plate 7* must be sufficiently above theplate 3 for free ingress of air. The lower edge of the shield plate rpreferably extends below the lower edge of the shield plate 'r andcurrents of air cannot blow in to make the flame unsteady. The uppershell act the lantern 1s perforated circumferentially at 5 and there isan outer shield plate 3 connected to the shell 0 above the perforationsand extending below said openings, and an inner shleld plate 8 isconnected to the shell 0 below the openings 5 and said shield plateextends above said openings and by this means a r is admitted into thetop of the lantern, but direct currents cannot blow in.

Within the top of the lantern I employ a conical or tapering tube taud achimney t with a flaring lower end and domes or hoods u 'u. The outertube 25 is connected to and suspended from the shell 0 by arms 6 andaround thetube t is a deflector 7 of' inverted cono dal form andfastened to this tube 15..

Within thetube t this deflector 7 prevents downward drafts of airblowing in 'under the dome o and compels the air entering by theopenings 5 to pass down close within the shell 0. The conicaldeflectingtube t is connected to and suspended from the tubet by arms;&

The dome or hood to is above the tube tand connected to it by bracketarms 9, and the dome or hood 0 is over the uppercase or shell 9 and isconnected to it by arms 10, there belng air spaces between the domes andshell or tube respectively.

The products of combustion pass up the tube or chimney t, over the topof the tube t and around beneath the edge of the dome it, over the upperedge of the shell 0, beneath the dome cand escape into the atmosphereand the wind is prevented from blowing in by the dome. The air thatenters the openlugs 5 passes between the shield plates 3 s and over thetop of the plate 8' and being cooler than the heated air in the centerof the lantern it passes down in the direction of the arrows tocommingle with the air passing to the flame. The outside of the lanternis thus kept cool and abundant air is supplied to the flame, and theflame is protected from the direct action of currents of' air. There isa slight upward movement of heated air between the tubes 25 and t, andthe tube t acts as a shield to prevent the radiation of heat from thetube or chimney t.

I claimas my invention-- upper part of the fount and surrounding thebase of the burner and beneath which the air tubes open for the passageand outward deflection of air before it passes up to the flame,substantially as specified.

2. In a lantern the combination with a perforated base a, of the oilfount, its imperferate flaring base g extending down below theperforations in the base a, the recessedbottom f, the perforated: plate6, vertical air tubes 11. extending through the top and; bottom of theoil fount,and the circumferential deflecting plate 0, substantially asset. forth.

3. In a lantern the eombinationwitha perforated base,a,,the shell aandnotched plate 3, of theremovable oil-fonnt f, its; lockingpin 2, theflaring baseg andcircular conical flange h, the edge of'the flange hfitting in the angle formed by the plate3 and shell a, whereby ingressof air between the fount and shell of the lantern is prevented,substantially'as set forth.

4. In a lantern the combination with the oil fount, burner andv glass b,of the base a, the lower shell 0. withperforations around the same, theouter and inner shield platesr r secured to opposite surfaces of theshell a and extending over such perforations with passages between theshield plates and through the perforations forthe ingressof air totheflame, substantially as specified.

5. In a lantern the combinationwith the oil fountand burner, of theuppershell c-with perforations around the same and. the shield plates 8 s,thetubes H, the domes or hoods u '0 over the tube tand shellrespectively, the brackets andarms by which the parts are connected toand supported by the shell c'and the deflector 7 around the tube 25,whereby the products of combustion escape by the tube 25 and air throughthe openings 5 in the'shell c is allowed to pass in betweenthe case andthe tubet, and the entrance of air beneath the dome o is prevented,substantially as set forth.
